Use this to cover up the gap between your desk and the wall. I got sick of stuff falling behind my desk.

The main file used is 5 pieces of 150mm that add up to around 30inch or a little over 2 feet

This won't work for all desks but you might be able to even scoot your desk back from the wall to make it fit.

PLEASE PRINT THE TEST PIECE FIRST!!!

I have included a small 20mm size to test the fit.
